Definitions

  • This invention relates to electro-acoustic transducers, and in particular to such transducers designed to be placed close to the eardrum, and to a resilient support device for maintaining their posi­tion relative to the eardrum.
  • Earphones and headphones are generally well known in the art. Both earphones and headphones have electromagnetic transducers, whether dynamic or static, for producing sound from electrical signals. Generally the distinction has been that an earphone includes a transducer held in the ear, possibly with a strap over the auricle, or outer ear, to hold the transducer in place generally at the ear. Headphones, on the other hand, have a transducer attached at one or both ends of a strap that fits on tcp of the wearer's head in such a position that the transducers are positioned generally at the ears.
  • the disadvan­tages of headphones, with their uncomfortable weight applied to the top of the head and the sometimes undesirable effect the headband can have on a woman's hairstyle, are well known.
  • the earphones As to the earphones, they have the distinct advantage that the transducer is held close to the user's eardrum, and the closer the transducer can be held to the eardrum, the better the sound fidelity will be.
  • earphones were held in place by a pipe that was inserted into the auditory meatus of the wearer, and sized so as to fit snugly therein, possibly aided by the strap over the auricle referred to above.
  • Such an earphone is shown in U.S. Patent No. 4,403,120 to Yoshimi, and described at Fig. 1(d) therein as "Prior Art". Since the pipe was generally made of a hard material, it could easily become uncomfortable if used for more than a few minutes.
  • This invention relates to improvements to the apparatus described above and to solutions to the problems raised thereby.
  • the invention includes an earphone, which is constructed of a housing, and a transducer comprising a magnetic circuit received in the housing and a diaphragm magnetically coupled to the magnetic cir­cuit.
  • the diaphragm has a diameter substantially equal to the housing.
  • a resilient support member is attached in relation to the housing and aligned with the diaphragm. In use, the resilient member is compressed, inserted into the user's auditory meatus and allowed to re-expand so as to provide a high fidelity sonic connection between the diaphragm of the earphone and the user's eardrum.
  • a protector plate is attached to the housing and covers the diaphragm. The support member is then affixed to the protector plate.
  • the support member is generally cylindrical in shape, having a longitudinal axis oriented generally normal to the diaphragm.
  • the support member includes an axial opening which runs substantially the length of the member.
  • This earphone assembly 10 constructed according to a preferred embodiment of the invention.
  • This ear­phone assembly 10 includes an earphone housing 12, carrying therein a transducer 14.
  • This transducer 14 includes a magnetic circuit 16, and a diaphragm 18 driven by the magnetic circuit.
  • the transducer 14 produces sound in a generally conventional manner in accordance with a signal received in the magnetic circuit 16, generally via a cord or wire 20.
  • the earphone assembly 10 includes a support member 22.
  • This support member 22 is attached in relation to the housing 12 in such a manner that the support member extends outwardly, away from the housing.
  • the support member 22 is generally cylindrical in shape, with an axis generally normal to the diaphragm 18.
  • the support member 22 may be attached in relation to the housing 12 by any suitable attachment means.
  • a protector plate 24 is provided to cover and protect the trans­ducer 14. Sound passage openings 24a are provided in the protector plate 24 to allow the sound generated by the transducer 14 to escape and proceed into the us­er's ear.
  • the support member 22 is attached to the protector plate 24 by any suitable attachment means, such as adhesive or sonic welding.
  • Further attachment support of the support member to the housing 12 may be provided by an annular flange 12a at the outermost edge of the front face of the housing, projecting generally parallel to the axial direction of the cylindrical support member 22.
  • the inside diameter of the flange 12a is sized so as to just fit over the outer diameter of the support member 22.
  • the support member may be adhered to the flange 12a by any suitable means such as adhesive or sonic welding.
  • An axially oriented opening 22a may be formed in support member 22. Such an opening 22a, allowing the sound generated by the transducer 14 to escape and reach the user's ear, runs generally the entire length of the support member 22.
  • support member 22 is composed of a foamed plasticized polymeric material having a sufficiently high concentration of plasticizer to provide the member with a reduced rate of recovery from compression, such as the material disclosed in U.S. Patent No. 3,811,437. That is, the support member 22 is compressible and sized, in its un-compressed state, larger than the user's auditory meatus. Because of its physical properties, once compressed, the member returns to its original, expanded state only slowly.
  • the use of the assembly 10 according to the present invention can be seen by reference to Figs. 4 and 5.
  • the user first compresses the support member 22 trans­versely, as shown in Fig. 4, so that the diameter is smaller than the user's auditory meatus 28 (Fig. 5).
  • the user inserts it into his auditory meatus 28, where it continues to expand until it contacts the interior of the meatus.
  • the apparatus and method of the present inven­tion provide good positioning of the transducer 14 at the entrance of the user's auditory meatus, substan­tially improving the sound fidelity heard by the user.
